REINFORCED WOOD PANEL.

Application filed November 16, 1912.

. and State of California, have invented new and useful Improvements inReinforced Wood Panels, of which the following is a specification.

This invention relates to a reinforced r wooden panel.

The object of the present invention is to provide a suitable reinforcingmeans which may be embedded and secured in the body of a panel for thepurpose of preventing warping or splitting of same.

A further object of the invention is generally to improve the art ofWood reinforcing so as to increase its utility and durability.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is aperspective view of a panel and tools employed for the formation of thegrooves in which the reinforcing material is placed. Fig. 2 is aperspective view of a panel showing the pockets and the reinforcingmaterial in position before and after the expansion of the pockets intonormal position. Fig. 3 is a similar view showing the formation of thegrooves for the reception of the reinforcing material.

The object of the present invention is to embed in the body of a woodenpanel a suitable reinforcing means which will pre vent warping orsplitting of same when exposed to heat or moisture caused by climatic orother conditions.

The embedding of the reinforcing material in the body of a panel isaccomplished in the following manner: A indicates the panel and 2 aseries of pockets or grooves formed in the back of the panel; the depthof these pockets or grooves being approximately half the thickness ofthe panel. The lower portions of the pockets 2 are connected withperforations or passages 3. The reinforcing material placed in-thesepockets may consist of a threaded wire 4, a twisted wire, a woodendowel, or a flexible reinforcing means, as a cord 5, shown in Fig. 3. Areinforcing material of this nature is forced through the panel by beingpassed through the pockets or grooves 2 and connecting pas-Specification of Letters Patent.

sages 3, and is secured in the panel with the ob ect in view ofpreventing splitting or warping of same. The means or method forsecuring the reinforcing material will later be described.

The pockets or grooves 2 are preferably cut by a chisel-shaped orsimilar tool. The tool or tools 6 employed in forming the pockets may bemounted upon a roller or similar well known device in such a positionthat the panel, when being passed under the roller, will be acted uponby the tools to form the pockets. The connecting passages between thepockets 2 may be produced by suitable means, as by a drill or a toolindicated at 6, Fig. 1, which may be mounted on a reciprocating member.Tools for this kind when entering crosswise of the grain in the wood,will first cut the fiber of the wood and then spread the fibers apart orcompress them endwise by the bevel of the tool being forced into thewood. A groove or pocket thus produced will close itself again on theapplication of water, as shown at 7, Fig. 1. The small fibers of thewood expanding, due to moisture, will come back in their former place orposition sufficiently to grip or secure the reinforcing material placedin the grooves, and will also tend to close that part of the pocket orgroove extending above the reinforcing material. By referring to Fig. 3,it will be seen that the same results may be obtained by forming onecontinuous groove across the face of the panel; the groove being formedby the same method as formerly described.

By employing the reinforcing material here shown and securing it byexpanding the wood, the panel becomes absolutely impervious to weatherconditions, as both moisture and heat will tend to more securely gripthe reinforcing material. I also wish it understood that a series ofpanels may be secured together by passing the reinforcing material, asthe threaded wire 4, through a whole series of panels, thus eliminatingthe necessity of joining the panels by other means, this producing areinforced Wooden partition with transverse metallic threaded or twistedwires embedded in same. The embedding of a twine or fibrous material,indicated at 5, in the panel is only desirable where the material is tobe re-cut and fitted for different purposes.

A panel reinforce as here shown can be built in different thicknessesand will thus not occupy more space than laminated panels heretoforeused. The reinforcing materials embedded in the wood are such asexperience and judgment of the manufacturer may dictate.

I wish it understood that various changes and minor details ofconstruction may be resorted to within the scope of the appended claimsand that I do not Wish to limit myself to the specific construction hereshown.

Having thus described my inventiomwhat I claim and desire to secure byLetters Patent, is-

1. The method of introducing a reinforcing strand into a wood panelwhich consists in severing the fibers transversely on the line of theproposed reinforcement without removing material and crowding back theends of said fibers to form a groove to receive the reinforcement,introducing the latter into said groove and permitting the expansionback of the crowded fibers to close the Wood onto and retain thereinforcing strand.

2. A reinforced structure comprising a wood panel, a series of pocketsin one side of the panel having the sides spread apart or compressedendwise of the grain, inclosed passages connecting said pockets, and areinforcing material extended through said pockets and communicatingpassages, the sides of said pockets being expanded to grip thereinforcing material.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
